Definitions
- the invention relates to a surface-treated abrasive grain based on aluminum oxide and an abrasive produced therefrom, in particular an abrasive applied to a base.
- Abrasives in the form of an abrasive paper which have large empty spaces between the individual abrasive grains and the cutting tips of all the abrasive grains lie in the same plane which runs parallel to the plane of a base.
- a synthetic resin or glue layer is applied to a base and then a number of abrasive grains are sprinkled electrostatically against gravity and thus used in an upright position in a first glue layer (DE-OS 21 25 942).
- the object of the present invention is to provide an abrasive grain which does not have these disadvantages.
- the amount of substance is preferably 0.1 to 0.5% by weight, based on the amount of abrasive grain.
- abrasive grain In order to determine whether the abrasive grain has the required properties, it has proven to be expedient to determine the specific resistance of the abrasive grain in granular beds. This is conveniently spec. Resistance at less than 3.5 x 1010 ohm x cm, preferably between 0.05 x 1010 and 2.5 x 1010 ohm x cm.
- an abrasive grain based on aluminum oxide is suitable in the micro and in particular in the macro range in accordance with the FEPA standard.
- Corundum such as high-grade corundum, semi-precious corundum, normal corundum, high-temperature-treated blue corundum, zirconium corundum, sintered corundum or corresponding single-phase or multiphase compositions are understood as grinding grains based on aluminum oxide. Mixtures of different corundums, e.g. Corundum, blue corundum, zircon corundum, sintered corundum can be used.
- a hygroscopic substance can be a carbonate, hydrogen carbonate, sulfate, nitrate, phosphate, fluoride or chloride of the metals of the 1st, 2nd or 3rd main group or the 1st or 2nd row of the transition metals of the periodic table, but advantageously sodium carbonate, sodium hydrogen carbonate, magnesium chloride , Calcium nitrate, iron chloride, each used alone or in a mixture.
- Finely divided metal oxides such as silicon dioxide, aluminum oxide or titanium dioxide, are used as hydrophilic substances, in each case alone or as a mixture with one another.
- the very finely divided metal oxides have a particle size of the primary particles in the d50 value of suitably 1 to 500 nm, preferably 10 to 50 nm, and a specific surface area between suitably 5 to 500 m2 / g, preferably 50 to 380 m2 / g.
- the abrasive grains can be used for different purposes.
- Abrasive grains based on aluminum oxide, which are coated with a hygroscopic and / or hydrophilic substance, are particularly suitable for the uniform coating of a base having an adhesion promoter in the electrical field.
- abrasives that are based on an abrasive grain that has been treated with the finest possible hydrophilic substance, excellent integration or adhesion of the abrasive grain on a flexible base or in abrasives with a synthetic resin bond is additionally achieved.
- Such abrasives are therefore particularly suitable for abrasive belts and grinding wheels that have to achieve high grinding performance.
- Known materials such as paper, plastics, linen or fiber-reinforced types of fabric are advantageously used as a base.
- An adhesion promoter is usually applied to this base on one side.
- glues or adhesives such as wood glue, bakelite, phenol, aldehyde, urea, formaldehyde, epoxy, polyester or polyurethane resins are suitable as adhesion promoters.
- the abrasive grain is treated according to the invention with a hygroscopic and / or hydrophilic substance.
- the hygroscopic substances are dissolved, the hydrophilic substances, if insoluble, are suspended in a carrier and the abrasive grain or the abovementioned are dissolved in this solution or suspension
- Mixtures of different corundums added and the solvent or the carrier is removed by drying, for example by drying, by evaporation or spray drying.
- the individual components must be weighed out in such a way that a coated abrasive grain with the proportions of abrasive grain and substance according to the invention results.
- abrasive grain is placed in a mixer (tumble mixer, rotary mixer, free-fall mixer) and dry-mixed with the substance selected from the series of materials mentioned or a mixture from this series.
- the weight ratio according to the invention is set by the appropriate choice of the amount of abrasive grain to substance.
- the treated abrasive grain can then be fed to the coating devices known per se and processed therein as is known.
- the scattering ability was tested in a laboratory tester under constant conditions, the percentage by weight of the grains adhering to an adhesive tape being taken as a measure of the scattering ability, which had to jump against the adhesive tape from an underlay in the electric field against gravity .
- the spec. Resistance values were measured with constant conditions in cylindrical grain beds (diameter 30 mm, grain quantity 2 g).
- Measuring device crank inductor 5,000 V, measuring range 1 x 106 to 4 x 109 ohms. The results are shown in Table I.
- Table I Dural HT grain 36 untreated treated with 0.2% Al2O3 A resistivity ohm x cm > 12 x 1010 0.4 x 1010 Scatterability% 8th 92 B resistivity ohm x cm > 12 x 1010 0.2 x 1010 Scatterability% 12 96 C.
- Example 2 The procedure was as in Example 1, only with semi-precious corundum as the abrasive grain, and it was treated with 0.2 wt.% Al2O3 by dry mixing. The results are shown in Table II.
- Table II Semi-precious corundum grain 36 (Abramant®) untreated treated with 0.2% Al2O3 A resistivity ohm x cm ⁇ 12 x 1010 0.4 x 1010 Scatterability% 26 96 B resistivity ohm x cm ⁇ 12 x 1010 1.5 x 1010 Scatterability% 32 96 C. resistivity ohm x cm 10 x 1010 0.6 x 1010 Scatterability% 50 97
- Dural HT grain 60 samples with hygroscopic substances (0.5% by weight) were prepared by dissolving the substances in water, adding the abrasives and evaporating them at 200 ° C. The spreadability was no longer explicitly measured here because the spec. Resistance is sufficient as a measure. The results are shown in Table III.
- Dural HT grain 36 was prepared with 0.01% by weight sodium hydrogen carbonate: Dural HT grain 36 untreated treated NaHCO3 > 12 x 1010 ohms x cm 0.1 x 1010 ohms x cm
